India is home to the world’s largest tribal population (8.63%), a large number of whom live in concentrated areas on rugged forest terrain. These Indigenous peoples used to live in a customary socioecological space for their survival. Through major and minor forest resource collection, tribes living along forest buffers have developed sustainable socioecological relationships with their environments. Traditionally, Indigenous people enjoy not only various benefits from living in forest environments but also escalating initiatives to improve the sustainability of those environments. Such interconnections with the environment secure their role as the most influential components of maintaining their ecosystems. Human–ecosystem interconnections happen within complex systems. This study examines the interspace between tribal livability and the socioecological environments in a forest ecosystem. A cross-sectional survey was conducted on Indigenous peoples in Jangalmahal district in West Bengal to monitor ecosystem services and tribal livability. Four ecosystem services in forests are interlinked with multidimensional aspects of tribal livability via the society, environment, livelihood, and food (SELF) method. This study’s results revealed that tribal livability significantly harmonized with environmental quality. Exploring such important connections not only helps to empower tribes but also emerges as a feasible way to improve the management of ecosystems.
